Question

Write a public method called reverse with one int parameter nums. It should reverse the elements of nums. It should not return anything it should modify nums in place.

Answer 1

To reverse the elements of an array in Java, you can create a public method called reverse with one int parameter nums. Inside the method, you can use a for loop to swap the elements of the array starting from the first and last positions until the middle is reached.

Step-by-step explanation:

To reverse the elements of an array in Java, you can create a public method called reverse with one int parameter nums. Inside the method, you can use a for loop to swap the elements of the array starting from the first and last positions until the middle is reached. Here is the code:

public void reverse(int[] nums) {
int start = 0;
int end = nums.length - 1;
while (start < end) {
int temp = nums[start];
nums[start] = nums[end];
nums[end] = temp;
start++;
end--;
}
}
